HYDRO'CARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 726,212, dated April21, 1903.

\ Application filed July 22, 1902. Serial No. 116,572. (No model.)

T0 at whom it may concern:

Be it known that I, TALBOT O. BATEMAN, a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, haveinvented a new and useful Hydrocarbon-Burner, of which the following isa specification.

My invention is an improved hydrocarbonburner especially adapted forburning crude oil; and it consists in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of ahydrocarbonburner embodying my improvements. Fig. 2 is a detailelevation showing the indicating-dial and the adjusting-lever. Fig. 3 isa similar view showing the atomizing-nozzle.

In the embodiment of my invention here shown there is provided amixing-chamber 1, of tubular form, having arms 2 3, at right-an gles toeach other, a globular portion 4 at the intersection of said arms 2 3,and an arm 5, to which a steam-pipe 6 is connected by a coupling 7. Apipe 8 to supply oil to the burner from a suitable source 'is coupled tothe lower end of the arm 3, as at 9. A pressure-indicating gage 10 isconnected to the globular portion 4 of the mixing-chamber.

To the outer end of the arm 2 is coupled a tube 11, which forms avaporizing-chamber that leads from the mixing chamber. A union 12 iscoupled to the outer end of the tube 11 or vaporizing-chamber .and formspractically an enlarged diametric prolongation thereof, and in the outerend of the union is screwed a head 13, which has a central opening 14,that tapers outwardly, and radially-disposed openings 15, which extendfrom diametrically opposite sides of the said opening 14, and the sidesofwhich openings 15 dichamber is filled with a packing of asbestos, asat 20. This construction enables the discharge portion of thevaporizing-chamber to withstand a very high temperature. The union 12and head 13 form a nozzle at the outer discharge end of thevaporizing-chamber.

Within the scope of my invention and the appended claims modificationsmay be made in the construction of the nozzle, and I do not desire tolimit myself to the construction herein shown and described. To theouter end of the arm 2 of the mixing-chamber is secured asupporting-plate 21. The same is here shown screwed to the arm 2 and isadapted to be secured by bolts or other suitable devices to 'the frontof a steam-boiler furnace, so that the same will support the burner withthe vaporizing-chamber thereof disposed within the fire-box of thefurnace. At the outer side of theglobular portion 4 of themixing-chamberis formed a bearing 22.

A jet-tube 23 extends longitudinally through the globular portion 4 andthe arm 2 of the mixing-chamber and also through the Vaporizing-chamber11, being concentrically disposed with reference to the latter, the arm2,

and the globular portion4, and the outer portion of the said jet-tube isscrew-threaded, as at 24, and. engages the threaded bore of the bearing22, so that the jet-tube is not only supported by the bearing, but isadapted to beturned so that it may be moved longitudinally. On the outerportion of the bearing 22 is screwed the hub portion 25 of anindicating-dial 26. The outer portion of the jettnbe extends through acentral opening in the indicating-dial, the latter being chambered, asat 27, for thereception of packing material to prevent leakage, and tothe outer end of thejet-tube is securedan operatingle'ver 28, by whichit may be turned, the said operating-lever being here shown as providedwith a pointer 29, which sweeps on the dial as the jet-tube is turned.The inner end of the jet-tube is disposed to discharge through theopening 14 of the nozzle, is tapered, and disposed within the saidopening, but does not entirely close the same. By turning the jet-tubeto move the same longitudinally'the capacity of the nozzle asrepresented by the opening 14 may be varied, as will be under- Iuustood. That portion of the jet-tube which is within the mixing-chamberis open to the admission of commingled steam and gases from the oil, andthe said jet-tube is here shown as provided with openings 30 for thispurpose.

The operation of my improved burner is as follows Steam under pressureand oil are admitted to the mixing-chamber through the pipes 61 8. Theoil is converted into gases in the mixing-chamber, which gases arethoroughly commingled with the steam and pass therefrom through thechamber 11, which is exposed to the direct heat in the interior of thefurnace and in which the commingled steam and gases are vaporized andfrom which the resulting vapor is discharged through the openings 14 and15 of the nozzle into the interior of the I furnace. A jet of thecoinmingled steam and gases is also discharged from the mixing-chamberdirectly through the opening 14 of the nozzle by the jet-tube. The vaporthus discharged by the jet-tube enters the interior of the furnace at alower temperature and in a more aqueous condition than that which isdischarged from the vaporizing-chamber, proceeds farther in the furnaceunder the boiler before being consumed than does the vapor which isdischarged from the vaporizing-chamber, and hence uniform combustion ismaintained in all portions of the furnace. The openings 15 discharge thevapor in lateral jets, the outer edges of which are broadened, owing tothe shape of the said openings 15, thus contributing to the equaldistribution of the vapor throughout the interior of the furnace and.

the uniform heating of all parts of the furnace. WVhere crude oil isused, an orangecolored flame, which is semitransparent and is intenselyhot, is maintained in the furnace,

and there is no smoke.

By adjusting the jet-tube as hereinbefore described the pressure in themixing and vaporizing, chambers of the burner may be regulated at will.The adjustment of the jet-tube is indicated by the position of thepointer 29 on the scale of the dial 26.

\Vhen the burner needs clearing out, which occurs very infrequently,this may be readily accomplished by moving the jet-tube outwardly asufficient distance to entirely uncover the tapered opening of thenozzle. The deposits in the burner will then be blown therefrom, as willbe understood.

Having thus described my invention, I claim 1. In a hydrocarbon-burner,the combination of a mixing-chamber, means to admit liquid hydrocarbonand steam under pressure thereto, a vaporizing-chamber leading from themixing-chamber and having a nozzle, and a jet-tube extending from themixing-chamber through the vaporizing-chamber, open at a point withinthe mixing-chamber to the admission of commingled steam and gases, anddisposed to discharge through, without closing, the nozzle,substantially as described.

3. In a hydrocarbon-burner, the combination of a mixing-chamber, meansto admit liquid hydrocarbon and steam under pressure thereto, avaporizing-chamber leading from the mixing-chamber and having a taperednozzle, a jet-tube extending from the mixingchamber through thevaporizing-chamber, open at a point within the mixing-chamber to theadmission of com mingled steam and gases, and disposed to dischargethrough, without closing, the nozzle, the one being adjustable withreference to the other to vary the capacity of the nozzle, substantiallyas described.
